GATHERING-POOL I EOR GLASS-TANKS.

Specification of Letters Patent.

Patented Nov. 2, 1909.

Application filed December 18, 1908. Serial No. 468,164.

To all whom it may concern:

' Be it known that I, ALEXANDER L. SCHRAM, a citizen of the UnitedStates, residing at Hillsboro, county of Montgomery, and State ofIllinois, have invented a certain new and useful Improvement inGathering-Pools for Glass-Tanks, of which the following is aspecification, reference being had to the accompanying drawings, forminga part of this specification, in which Figure 1 is a vertical sectionalview through a portion of a glass-tank, showing, also in verticalsection, my improved gathering-pool in connection therewith; Fig. 2 IS aperspective view of the athering-pool blocks detached from the tan Fig.3 1s a plan yiew of the gathering-pool basm block, showing incross-section the depending lip or lug of the gathering-pool upper blockin cooperative relation to said basin block; and Fig. 4 is a fragmentarvertical sectional V ew of the glass-tank, slowing, also in vertlcalsection, the gathering-pool with a perforated cover-block thereon.

This invention relates to a new and useful improvement ingathering-pools for glass tanks.

The objects of my invention are to so construct or provide glass-tankswith gathering-pools on the outside, but having communication with theinterior, thereof, so that the molten or fluid glass in condition to beworked may be readily and easily obtained; to provide means for sealingthe outlet-openmg from the tank to the said pool, whereby, although theflow of molten or fluid glass from the tank into said pool is notinterfered w th or hindered, the hot air or gas within said tank andupon the body of molten glass therein for maintaining the same in acondition of fluidity is prevented from escaping from said tank throughsaid opening an the entrance of cold or atmospheric air through saidoutlet-opening into said tank, which cold or atmospheric air would tendto reduce the temperature of said hot air or gas and chill or hardensaid body of molten glass, is prevented; and to provide in or about saidgathering-pool means whereby the glass therein is maintained in a fluidor plastic condition to be easily worked as required.

With these objects in view, my invention consists in the novel parts andin the novel construction, arrangement, and combination of the same, allas will hereinafter be described and afterward pointed out in the Iclaims.

The glass, as is usual, is first melted in a glass-furnace, not shown.In said furnace the glass is melted to a condition of perfect fluidityand the scum and other impurities are. removed or settle at the bottomof the v furnace. From this furnace the fluid glass flows through asuitable opening therein into tank 1, the body of molten glass in tank 1bein indicated by the numeral 2. The flow 0 glass fromsaid furnace intotankl may be regulated by suitable valves or other means, and the bodyof molten glass 2 in tank 1 is usually and referably maintained uidstate and in condition range outside the wall of said tank, but incommunication with the interior thereof, one or more of mygathering-pools 4. Each vof these pools comprises a basin-block 5 andwhat might be cal ed a deflector or sealing block 6, both said blocksbeing referably of refractory material. The bloc 6 is provided a itsouter middle portion with a depending projection or lip 7 adapted toextend downwardly a short distance into the concavit or basin of block5, for purposes hereina ter appearincg. Block 6 is also under-cut orchamfere as at 8, in and from the middle rear portion thereof,preferably at an angle, toward and terminatmg at the 1i 7, the sideportions 9 of block 6 being adapted to rest on the sides 10 of block 5when the said blocks are arranged in cooperative relation. Therearportion of the concavity in the basin-block 5 is inclined downwardlyand inwardly, as at 11, so that when said blocks 5 and 6 are inposition, an inwardly flaring o ening into the pool 4 is rovided in thewa l of tank 1, the up or en of said inclined Wall 11 being re erablyand substantially in alinement with the of block 6. The blocks 5 and 6are adapted to be built in or otherwise embedded in the sidewall of tankland are preferably so positioned therein that the up 1' face or top ofbasin-block 5 is substantia l'y on a level with the glass-line wa m,whereby there is maintained a steady supply of molten or fluid glass inthe pool 4, the glass flowing easily and in a comparatively heavy massinto said pool 4 through the said flaring opening thereinto. Thedepending lip 7 of block 6 now projecting downwardly into the body ormass of molten glass at the rear of 001 4 forms or provides a seal,which e 'ectively prevents the entrance of the outer cold air into saidtank 1 through the opening into pool 4, whereby the temperature withinsaid tank is not reduced, and also efiectively. prevents the escape ofthe hot air or gas from within said tank to the exterior, so that thecondition or state of the body of glass 2 is not afiected by having saidoutlet-opening into said pool in direct communication with the interiorof said tank. The undercut or chamfered wall or side of block 6 enablesthe hot air or gas in tank 1 to be deflected or applied upon the glassclose to the the pool 4,and due to the inclined wall 11 of block 5, andthe gradually decreasing depth of the concavity in block 5 leading intosaid pool, a substantially heavy stream or mass of molten glass isbrought directly to said outletopening into said pool 4, whereby theglass as it enters pool 4 is prevented from becoming sticky or lumpy andis in a substantially perfect condition to be worked as desired, theglass being adapted to be taken from the pool 4 by suitable tools ormeans in quantities sumcient for the purpose or use to which the glassis to be put. In order now to maintain this condition of the glass whilein the pool .4 and to prevent the glass while therein from hardening, Ipreferably provide fiues 12 in said basinblock 5 around the periphery ofpool 4, into which fines are admitted, and through which are assed,products of combustion preferably from an oil or gas fuel burner 13provided and arranged so as to supply the heat to said fiues in anydesirable manner and as clearlyshown in Figs. 1 and 4. The flame fromthe burner .13 may, of course, be regulated by a suitable valve 14 and afuel supply-pipe 15, as is well understood. If desired, the burner 13and supply-pipe 15 and also the outer portion or wall of pool 4, asshown in F igs; 1 and 4, may be incased by a protecting brick or otherwall 16, although this wall may be dispensed with. Thus, by means of theroducts of combustion from burner 13 passmg into and through the fines12, the inner surface of pool 4 is heated and the glass within the poolis maintained in a plastic or molten state, in order that when takentherefrom it may be satisfactorily worked.

In some instances, if desired, I may provide for the pool 4, as shown inFig. 4, a perforated cover-block 17, which is provided withflue-openings 18, adapted to register outlet opening intowith flues 12in block 5, in order to permit the exit of the products of combustionthere from, and with a central opening 19,-throughj which the gatherintool may be inserted to take or remove rom pool 4 the desired quantityof glass.

By my construction, it'is thus seen that I provide a gathering-pool onthe outside of the glass-tank from which the desired quantities of fluidor plastic glass may be readily and easily taken, the glass as it enterssaid pool and while in said pool being kept or maintained in asubstantially perfect molten or fluid state to be satisfactorily worked.

It is, of course, understood that the blocks 5 and 6 may be made invarying sizes, as desired, for various sized tanks; that the cover-block17 may be made in varying sizes to fit various sized pools; that thediameter of the central opening in'said cover-block may be regulated toaccommodate different kinds of gathering-tools; that cover blocks havingcentral 0 enings of various dlameters or sizes may be interchangeablyused on the same pool; and also that other minor changes in thearrangement and construction of the several parts of my pool may be madeand substituted for those herein shown and described without departingfrom the nature and principle of my invention.
